I'm having a brainfreeze! I've forgotten how to work out the percentage reduction between two prices. The starting price is 4450 and the reduced price is 3575, so what's the percentage discount? How do you work this out? The main problem I have is that I need to calculate a discounted price at the same percentage from a different price.

Thank god it's not Monday or I'd have no chance!

Thanks!
